- As non-metallic mineral resources, has important defense strategic role- Can be used for high and new technical projects, is of great economic and social benefits - Is the metallurgical industry refractory material - Is the chemical industry all kinds of corrosion of vessels, general equipment of carbon products

- Light industry is in pencil, ink and the main raw material of artificial diamond

Q:What's the difference between blue and red Panasonic batteries (carbon)?

Blue is leak, proof, general, Purpose, general use battery (leak proof)Red is the long life long life battery (suitable for watches and clocks and other small power appliances)And heavy duty green seems to be good for high power appliances, such as toy cars

Q:Why does the carbon content of steel increase and the mechanical properties change?

Q:Is the hardness or softness of the steel with higher carbon content?

Carbon is the major element in determining the properties of steel, because changes in carbon content lead directly to changes in crystal structure.

Q:I bought a grill myself and went to barbecue with my friends the day after tomorrow, but I can't ignite the carbon. What should I do?

Is it barbecue in the field? If so, there are many ways to ignite carbon in the wild.The simplest, affordable way is to pile up the fire, and then use the charcoal on it, charcoal will be used after burning.At home, it is placed directly on the gas range, ignited.Charcoal direct ignition is not convenient, it is best to use other things as medium ignition.Be careful when you're in the barbecue. Watch out for the fire.

Q:Iron and steel are different in terms of carbon content

. An iron carbon alloy with a carbon content of less than 2% is a steel, and a carbon content of more than 2% is called iron. Steel is widely used because of its toughness, elasticity and rigidity. Life is exposed to steel, but people call different. For stainless steel, whether or not the magnet is sucked on or not, as long as the quality standards are met, it is stainless steel. Therefore, from the perspective of metallurgy said, no rust said. The main element of stainless steel corrosion resistance is chromium. If the content of chromium is above 10.5%, the steel will not rust. When smelting, the alloy elements added are different, so there is a difference between the magnet and the suction.

In general, we use office A4, A3, B5 and other specifications of office paper are better offset paper, excellent offset paper to UPM and APP for the domestic leader.55G-140G grams in general, some mills also produce high grams, generally belongs to industrial paper!Carbon free copy is just typing paper and coating. Paint is divided into two kinds, one kind of colored, one kind of colorless.Generally for 37G, 45G, 52G and other grams.

Q:Rod box material, there is a kind of material called carbon fiber, who knows this material is good?

Very good, carbon fiber is made of organic fiber after a series of heat treatment into, inorganic fiber with high performance carbon content is higher than 90%, is a new material with excellent mechanical properties, the intrinsic properties of natural carbon material with, and both the textile fiber soft processing, is a new generation of fiber. Carbon fiber is a new dual-use material for military and civilian use. It is the key material of technology intensive and politically sensitive. It is the only material that does not drop in the high temperature inert environment above 2000 degrees celsius. Carbon fiber steel accounted for less than 1/4, the tensile strength of composite is generally above 3500Mpa, is 7-9 times that of steel, carbon fiber has superior corrosion resistance, it can also be safe and sound in the dissolution of gold and platinum "aqua".

Q:What is the difference between carbon and carbon materials?

Carbon refers to elements. Carbon materials usually refer to materials that contain carbon and are the main bodyCarbon is a carbon containing substance of no composition and property consisting of carbon elementsCarbon materials are usually specified, especially carbon and graphite materialsCarbon material is a broad carbon containing materialAbove.

Q:Method for making carbon fiber board

Our carbon fiber board adopts autoclave molding process, the product quality is good, no white spots, bubbles, lines and other defects, factory direct supply in bulk, at the same time to provide CAD customized processing services.Autoclave molding technology has the following remarkable advantages: high volume of fiber components, good quality stability, simple molding process

Q:What are the basic structures of iron carbon alloys?

Ferrite: a solid solution in which carbon is dissolved in alpha -Fe, called ferrite. The symbol is Fe. Ferritic carbon content is very low, at 727 degrees of 0.0008%, and its mechanical properties similar to pure iron, strength and hardness is not high, plasticity and toughness good.Austenite: a solid solution in which carbon is dissolved in gamma -Fe, called austenite.
